AXLE-SKEIN.

SPECIFICATION forming part of Letters Patent No. 374,473, dated December6, 1887. Application filed August 22, 1887. Serial No. 247,566. (Nomodel.)

12) all whom it may concern:

Beit known that I, EDMUND N. HATCHER, of Columbus, in the county ofFranklin and State of Ohio, have invented a new and IrnprovedAxle-skein, of which the following is a full, clear, and exactdescription.

My invention relates to an improvement in axle-skeins, and has for itsobject to provide a device which may be readily manufactured and inwhich angular indentures in the edge surfaces are avoided in cutting theblank, thereby avoiding danger of cutting too deep with the ends of theshears and weakening the skein by furnishingastarting-pointforabreak,and also wherein the skein will take an axle without trimming the same,and fully protect the wood at the point of intersection with the skeinand a distance beyond the same.

The invention consists in forming an axle skein of a single piece ofmetal and in cutting the blank in such manner that angular recesses inthe edges are avoided, and also in the details of construction, as willbe hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a side elevation ofthe axle-skei'n. Fig. 2 is a centrallongitudinal section through the same. Fig. 3 is a plan view of theblank. Fig. 4 is a transverse section through the enlarged portion ofthe skein, and Fig. 5 is a transverse section through the inner end.

It is the object of the present invention to so shear the shape or blankas to entirely avoid shearing an Lshaped recess in the same, or anyrecess wherein the shears points are liable to start splitting, therebyweakening and rendering possible a snap, split, or break under heavystrain or in trying positions. To that end the blank A is cut square atthe ends a and a, and from the outer edges of the front end, a, thesides are cut in a straight line toa point, m at the front of thecenter, the said lines being projected outwardly in opposite directionstoward the rear end, whereby the inclined side edges, I), are produced.From the point a the front side edges are curved outward to produce aslight concavity, 12', ten ininating at or near the centerof the blank,

and the metal at the center is cut straight across a short distance,then downward and inward with a full curve, d, and outward to the rearend in a straight line, d, thesaid lines 01 having an inclination fromtheir point of junction with the curve 01 inwardly and rearwardly, thecorners produced by their union with the rear end being beveled off, asshown at d, Fig. 3. Thus the blank comprises a wide front end, centralside wings or extensions, D, and a reduced rear end.

In further carrying out the invention the side edges of the blank arebent upward to ward each other and the edges from the outer end of thecurve (I extending forward are welded or otherwise firmly secured one tothe other. .As a result of the attachment :1 round tapered spindleportion, D, is produced,upon which the .wheel or hub-box is to revolve.At the butt or inner end, 6, of the spindle a metallic collar or band,E, is seen red by welding or shrinking, and to the rear of the collar Ean upwardly-curved bonnet, F, is formed, extending from the axle-butt eto a point, 0, near the center and horizontal to the extreme up perpoint, 6 as shown in Figs. 1 and 2, the said bonnet commencing round atc and ending at e in an oblong or 0 shape, asillustrated in Fig. 4. Therear end of the skein-that is, from the central point, e' t0 the endaforms an integral truss-extension, F, curving upward to meet thebonnet, and to the rear of the curve the said truss-extension issubstantially Ushaped in cross-section, as shown in Fig. 5. The skeinsusually break at 6 but my skein, made from a plate or blank having thedownwardcurved shear d, causes the extension to act as a brace, thatcannot do else than greatly re-enforee the weak point and act as a trussbetween e and a.

Ourvinglthe bonnet upward, as shown and described, admits of theadmission of a greater amount of wood or timber than heretofore, and byreason of the peculiar shape of the truss the axle need not be hewedfrom its sawed shape, whereby it is weakened, and the oblong shape ofthe bonnet will cause the use of sufficient timber to make the axleequal to almost any emergency.

By making my skein without a short bevel I avoid cutting notches ormaking a beveled hump, and am enabled to make a sheetmetal skein with anextension sleeve thoroughly braced from end to end and entirely freefrom angular cuts, which often cause a split or break and weaken theskein more at one point than at another.

The gradual upwardly extending bonnet commencing at 6 when the collar ismade fast enables me to do away with cutting the usual notch or bead,forming a hump to act as a hub or box rest. v

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The blank A, for a thimble-skein, herein shown and described, havingits sides formed with opposing wings D D, inclines b b d d at oppositeends of its sides, and the curved or rounding portions 1/7) and d clbetween the wings D D and the inclines Z) Z) and d (1, respectively,substantially as set forth.

2. An axle-skein formed of a single piece and with a round taperingspindlesection, D, an oblong bonnet, F, curved gradually from the pointe to the point e and horizontally to the extreme upper point e, and therear trussextension, F, curving upward to the bonnet, as at d 65,substantially as set forth.

8. An aXle-skein made from a single piece of metal and composed of atapering spindlesection, an upwardly-extending and integral hoodcircular in cross-section at its intersection with the spindle andoblong at its outer end, and a rear trussextension U-shaped incross-section, united with the hood by a curved edge surface, wherebyangular recesses are avoided, as and for the purpose set forth.

4. An aXle-skein made from a single piece of metal and composed of atapering spindlesection, an upwardly-extending anddntegral hood circularin cross-section at the intersection with the spindle and oblong at itsouter end, a collar secured to the spindle at the intersection of thehood, and a rear truss-extension U-shaped in cross-section, having itsin ner side edges concaved at their union with the hood, as and for thepurpose herein specified.
